Troubleshooting

Oil burners that are designed for use on road maintenance equipment are built to take temperature extremes, vibration, and rough handling. When performing the following troubleshooting steps, we assume that the oil burner motor and ignition transformer operate continuously and the oil solenoid valve, which controls oil flow, is cycled by the equipment controls. We also assume that there is power to the burner and fuel in the tank.

In addition to typical mechanics tools, it is recommended to have the following equipment on hand.

○Meter capable of measuring volts, ohms and amps,

○ignition transformer tester,

○smoke pump tester,

○combustion analyzer, and

○0 to 200 psi pressure gauge.

See Table 3 on following page for troubleshooting steps.
